A State Rarity Rank of S1 means: Typically 5 or fewer occurrences, very few remaining individuals, acres, or miles of stream, or some factor of its biology makes it especially vulnerable in New York State.

Global Rarity Rank:G5

A Global Rarity Rank of G5 means: Demonstrably secure globally, though it may be quite rare in parts of its range, especially at the periphery.

Dragonflies in the Clubtail family of the genus Stylurus are known as the Hanging Clubtails. They get their name from their perching behavior. When they perch on leaves in trees, their weight can bend the leaves downward until they are "hanging" almost vertically (Dunkle 2000, Mead 2003).

The Russet-tipped Clubtail is known to occur in seven counties in New York State, with no population estimates determined. Further survey efforts may result in the identification of additional populations, range expansions, or enable population sizes to be estimated.

No estimate of population size for the Russet-tipped Clubtail has been made based on observations made in the early and mid-1990s (New York Natural Heritage Program 2007). Information prior to this time frame is limited. Therefore, any new location information on the Russet-tipped Clubtail in New York may reflect heightened interest in surveying for this species rather than a population increase or a range expansion (Holst 2005).

Recent observations of Russet-tipped Clubtails have been made in Columbia and Dutchess counties, New York in the early 1990s. General reports of observations made also include locations in Albany, Greene, Putnam, Rockland, and Warren counties, as well as on Long Island (Gebauer et al. 2005, Donnelly 2004). Since these are fairly recent records, and the full extent and size of the populations have not been determined, long-term trends are unclear.
